librbd: deep_copy: update end_size only if zero interval caused truncate

The problem shown up when stripping was used, and assembling a
nonexistent destination object from source objects, and one of these
objects existed and snap diff returned a zero interval. The non-zero
end_size in that case triggered invalid object map update.
